Hi Yaswanth
I haven’t made it in real life, but doesn’t seem difficult.
What I would do is publish the default route with a different community in each hub (i.e. 65000:1 in one hub and 65000:2). In each spoke, depending of what you want use the community to set a local preference.
i.e.
in the hub:
router bgp 65000
network 0.0.0.0 mask 0.0.0.0
neighbor 10.0.0.2 remote-as 65000
neighbor 10.0.0.2 send—community
neighbor 10.0.0.2 route-map NY out
route-map NY permit 10
set community 65000:1
in the spoke:
router bgp 65000
neighbor 10.0.0.1 remote-as 65000
neighbor 10.0.0.1 route-map hub in
route-map hub permit 10
match community 65000:1
set local-preference 130
route-map hub permit 20
match community 65000:2
set local-preference 90
Regards, Fernando
